I am having a think about this....I would have guessed several recordings, but you stipulate small forces and that rules out a number I would have suggested.
I may well be off beam here, Virgin are owned by EMI and I am not sure whether they ever grab Virgin recordings for bargain boxes, but this version fits the bill and I know has been included in a box set of all the major Bach choral works.

It is a good version, plenty of colour and energy.
The following is a famous older EMI version, it has been endlessly repackaged, it is excellent in many ways, but it is not small in scale...

The following cannot be the version you heard, but I do love it. In its time it was revolutionary in that Rifkin, the conductor, made this case for it to be sung one to a part, so the scale of it is tiny in contrast to Klemperer. It is cheap, as are all those I have suggested so far. But it is not EMI.

Perhaps someone else can suggest a version I have not thought of that could be your version.
